WINDING MACHINE. l

Application led January 13, 1927'. Serial No. 160,966.

This invention relates to improvements in winding machines for Windingcops, cones or packages of yarn, thread and other attenuated material,and particularly to windt ing machines in which the cop or package isrotated through contact with a friction drive-roll or drum.

The resent invention is directed more particu arly to the means forcontrolling the .l movement of the copor cone-holder awa from thedriving-drum as the package buil s up thereon and for eiiecting theautomatic stopping oi. the machine when the cop or package reaches apredetermined diameter.

nUne object of the invention is to provide a machine of the typespecitied in which the stopping-mechanism may be set to wind packages ofany predetermined diameter through a. simple adjustment of thecontrolmeans.

Another object ot the invention is to proride a stopping-mechanism whichautomatically removes the cop from Contact with the drive-roll after ithas reached the predetermined diameter and which also disengages thestrand of yarn or thread from the coninuous'lypperated traversingthreadoru1 e. u Another object of the invention is to protu vide means'for resetting the stopping-mechanism of the winding machine undermanual control to prevent unwarranted stopping of the machine before thewinding operation gets under way to pick up the'threadand take up theslack in the delivering strand.

Another object. of the invention is to provide a controllingandstopping-mechanism for the winding machine which is more eilicient inoperation and less liable to derangement or getting out of order.

Further objects of the improvement are set iorth in the followingspeciiication which describes a preferred embodiment of the invention asillustrated in the accompanying drawings. lln the drawings:

Referring lirst to Figs. l and 2 of the drawings, 2 designates therotating drive roll or friction-drum from which the cop or package isdriven; 3 the rotating copholder or mandrel on which the cop is Wound,1n the present machine illustrated in the form of a cone-holder; 4 thereciprocating thread-guide which traverses the strand of yarn or threadlongitudinally of the copeholder to deposit it in helical coils thereon;and the rotating cam which rcciprocates the thread-guide 4.

The drive-roll 2 is mounted on a rotating shaft 7 which is drivencontinuously from suitable power mfeans not herein shown. Usually, thepower-shaft 7 is continuous for receiving a plurality of drive-rollsarranged at intervals along the machine frame which vcarries' a numberof winding units or heads.

In the present embodiment the cone-holder 3 is rotatably mounted on aspindle 8 carried bv a bearing 9 which is swiveled at the end of an arm10, see Fig. 2. The arm 10 is hinged on a pivot-stud 11 held in abracket12 mounted on the machine frame-member 6, whereby to support thecone-holder 3 in position to bear against the drive-roll 2 and to adaptit to swing upwardly therefrom in an arcuate path as the coneor packageis built up on the holder. The cone-holder 3 is adapted to tilt on itsswiveled bearing 9 as it moves upwardly away from the driveroll 2 toregulate the taper on the periphery of the cone being wound themechanism for controlling this action being illustrated in general at i3as embodying the construction shown and described in an application forUnited States Letters Patent Serial Number 126,897, filed August 3,1926.

The thread-guide .4 is mounted at the front lot the drive-roll 2 toadapt it to reciprocate longitudinally thereof. As herein illustrated,the thread-guide 4t projects upwardly from a slide lll which is slidableon a horizontal bar or rod 15. A second horizontal har 16 extends inparallel relation above the rod 15 and is engaged by a hooked bearing 17on the back ot the guide 4 to maintain the latter in erect position asit slides on the rod 15. The rod 15 and bar 16 are secured in place atthe front of the machine by lneans ot suitable bearing-blocks '18, seeFig. 2, which clamp them against the vertical arms 19 forming a part ot'the frame-members The slide 14 is provided with a lug 22 through whichextends a. stud 23 carrying a bowl or roller 24 at its lower end whichengages with the helical groove 25 in the cam 5. As herein shown the cam5 has a second groove 26 of different pitch in its periphery which maybe alternatively employed to reciprocate the guide 4 in the manner asknown in the art. vThe cam 5 is carried on a continuously rotating shaft27 which extends throughout the length ot' the machine frame to operatethe cams for other winding units mounted thereon. 1t will be apparentthat the rotation of the cam 5 causes the guide 4 to reciprocate backand forth at the front of the drive-roll 2, and the upper end of theguide is inclined inwardl toward the point of contact of the cop with7the periphery of the drive-roll and provided with a suitablethread-groove 28 through which the strand y leads to direct it onto thecop. The guide 4 is also provided with a hook 29 overlying its face t0adapt it to pick up the strand of thread or yarn to lead it into thethread-groove 28. The above described instrumentalities constitute theessential elements of the winding mechanism of the machine and aresimilar in general construction and arrangement to those heretoforeemployed in the art.

It has been noted that as the cop or cone Y, see Fig. l, builds up onthe holder 3 the latter swings upwardly on the arm 10, and suitabledogging-means are usually provided for steadying the motion of thecone-holder' and preventing a retrogressive movement thereof. Thepresent lnvention contemplates the employment of an improveddogging-mechanism for this purpose which provides for greater simplicityof construction and is adapted to cooperate with the sto ping-mechanismof the machine to arrest-t e winding operation when the cop or packagereaches a predetermined diameter or size. As herein illustrated thedogging-mechanism comprises an arcuate slide yor quadrant 30 whichdepends from the swinging arm 10. Referring to Figs. 2 and 7, thequadrant 30 is held in an arcuate slot 31 on the side ot the arm l0 andis clamped in position by means of a bolt 32 and washer 33 overlyme' itsside. Through this arrangement the quadrant 30 may be adjusted in theslot to regulate the extent to which it projects below the arm 10, thisadjustment providing for setting the quadrant tx) trip thestopping-mechanism when the arm 1t) has been moved upwardly to a)redetcrmined extent in accordance with the diameter ot' the cop orpackage to be wound.

The (logging-means which cooperates with the quadrant 30 to actl'rictionally thereon to prevent retrogressive movement of the arm 10consists of a sliding rod or bar 35 which also forms the tripping-meansor trigger for the stoppiiig-mechanism. As shown in Figs. 2 and 3, theslide 35 is mounted to slide through a slotted hearing 3G formed on anextension 37 ot the hrm-kot l2. The slide or bar 35 is provided with twolongitudinal slots 38 which are engaged hy pins 39 and 4() to hohl theslide in suspension; the rearward pin 39 being driven through the sidesof the slotted bearing 36 and the forward pin 40 projecting from theside of the l'iearing-block 18 previously referred to as fastened to thearm 1t) of the frame-member 6. At the rearward end o"v the slide 35 isan upstanding inclined arm 4. formed with a beveled face 43 which isadapted to engage the forward convex face ot' the quadrant 30, see Fig.2. A spring 45 is held against the rearward side of the bearing 36 withits opposite end bearing against. a pin 46 driven through the slide 35whereby it acts to urge the slide reaivwardly to cause its end 43 tobear against the quadrant 30 to frietionally resist the movement ot thequadrant across the slide. As a result of this construction andarrangement the slide or dog 35 is caused to bear against the quadrant30 to resist the upwa rd swinging movement ot the arm 10 as the packagewound on the holder 3 increases in diameter and to also act frictionallyto check retrogrcssive or downward movement of the arm. The movement ofthe coneor cop-holder 3 away from the drive-roll is thus frictionallycontrolled to provide a smooth, vibrationless motion whereby the cop orcone is prevented from jumping and rebounding with respect to thedrive-roll.

As a novel and improved feature of the present invention thedogging-mechanism is designed to vary the rictional resistance to themovement of the copor cone-holder as the cop or cone increases indiameter. That is to say. the. (logging action is differential inaccordance with the growth ol' the package,

,the resistance to the movement of the cone holder being at its maximumat the heginning of the winding and gradually dccreasing as the packagegrows in size and weight. This differential action is in accordance witha well-known principle ot winding based on the fact that more pressurecan be applied to the package when a relatively small body or masssurrounds the holder than when the yarn mass reaches a considerablediameter so that it is softer and more desirable to compress the firstlayers of lltl windin tothe maximum density to provide a' lirmondationujor subsequent la ers and this result is obtained by applymgt emaxlmum pressure tojthe copor cone-holder'at the start ofthe winding andgradually decreasing the pressure as the package 1ncreases indiameter.,.'l`his result 1s secured in the present invention by a noveland 1ngenious arrangement of the quadrant 'which is disposed ineccentric relation to dlill llll liti

llll

lit

the pivot 11 of the swinging arm 10..` By reference to the dotand-dashline in Fig. 2, which defines an arc struck on the pivotal axisiof thearm 10, it will be noted that the quadrant 30 does not conform to thisarc, but on the contrary is dis osed eccentric thereto. It will also benote that the upper part of the quadrant 30 is of .greatesteccentricity, being furthest removed `from the axis of the arm 10,'whilethe lower depending portion of the quadrant gradually approaches theaxis. It will thus be apparent that with the cone-holder 3 bearingagainst the drive-roll 2 .at the start of the winding, as shown in Fig.2, theslide or dog will be forced back to holdthe spring under maximumcompression; while as the coneholder arm 10 rises the diminishingeccentricity of the quadrant 30will cause the slide 35 to graduallyslide to the right to reduce rthe compression of the spring 45. ln thisway the friction action of the dog 42 nn the quadrant 30 is reduced togradually decrease the resistance to the sliding motion af the quadrantand thereby the resistance to the upward movement of the coporconeholder 3. It will be observed that through this simple arrangementand construction ap ecient mechanism is provided for applying resistanceto the movement of the cop or cone-holder away from the drive-roll witha differential pressure in accordance' with the increase in size of thepackage being maand.

lt has been stated that the slide 35 acts.

asthe trip for the stopping-mechanism ofthe machine, the dog 42beingadapted to slide olf from the end of the quadrant 30 afterthepaclrage has reached a predetermined dianieter in accordance with theadjustment of the quadrant on the arm 10. The instrumentalities whichcooperate with the slide 35 to arrest the Winding operation areillustrated in detail in Figs. 3 to 6 and will be next explained. Toarrest the rotation of the copor cone-holder 3 the arm 10 is lifted toremove the package from contact with the drive-roll 2 as is the usualpractice in machines of the present type. The lifting of the cone-holder3 is accomplished by positively raising the arm 10 by means of aratchet-mechanism, shown in detail in Fig. 5,-

which acts on the quadrant 30. It will be notedfrom this view that thequadrant 30 is formed with ratchet teeth 49 which are on the rearwardside of the uadrant asviewed in Figs. 2, 3 and 4 so t at they do notshow in full in these views. Adapted to engage the teeth 49 on thequadrant 30 is aJ pawl 50 which is pivoted at 51 to a swinging lever 52,see Fig. 5. The pawl 50 has a tail-piece 53 acted upon by a plunger 54'which is under the pressure of ,a sprlng 55 held in a poclet dependingfrom the lever 52. The spring 55 maintains the pawl 50 in engagementwith the teeth 49 and preferably the bearing of the pawl on its pivot 51is made more or less loose to provide play so that the pawl may adjustitself'to the teeth ivhen the quadrant 30 is moved a distance less thanthe length of a tooth.

The lever 52 is ixedly secured to the end of a rod 56 which is rockablymounted in a bearing 57 forming a part of the bracket 37 on theramemember 6 as shown in Fig. 2. The rod 56 has a second bearing 48 atthepfront of the frame-member 6. The rod 56 also forms the lock ordetent for maintaining the stopping-mechanism normally inactive, `itsforward end being bentfinto a crook at 58 and terminating in an inclinedarm 59 formed with a pointed detent-blade 60, see Fig. 6. Thedetent-blade 60 is adapted to engage a notch or shoulder 61 on a"latch-plate 62 which is fastened to the top' shown in Fig. 2 with itsupper end engaging A the hooked end 68 of an ar'n 69 on the lever 52. Astopescrew 70 screwed through the arm 69 and locked in place by achecknut 7l is adapted to strike against the top of the bracket 37, seeFigs. 2 and 5, to lirnitthe rocking-motion of the lever 52 under theaction of the spring 67. When the detentrod 56 is released the spring 67will rock the lever 52 carried thereon to lift the pawl 50 to a certainextent as regulated by the adjustment of the stop-screw 70. The liftingof the pawl 50 in this manner acts through the ratchet on thequadrant'() to slide the latter upwardly Awhereby to raise the arm 10 tolift the package, indicated at Y in Fig. 3, out of contact with the 4 l.guapas l drive-roll 2'to arrest the winding operation it is necessarythat the strand y belifted out of the groove in the guide to prevent theyarn or thread from being cut orl broken.;I The rockable member 65,previously ref erred to as carlyinv the latch-plate 62, constitutes' thethrea lifter for disengaging the strand y from the thread-guide 4. Asshown more particularly in Figs. 1 and 3, the threadlifter 65 isconstructed in the form of a relatively fiat plate provided withopposite socketed bearingsy 7 -l\ which are supported ou trunnion-pins75 projecting inwardly from the frame-members 6. Studs'76 are screwedthrough the. bearings 74 to en age beneath the pins 75 to hold thethread-lifter in lace on its trunnions' to pivotally support it terefrom. Asy shown in Fig. 2,-the thread-lifter 65 normally assumes aposition with its upper edge at the rear of and below the guidlng-groove28 in the thread-guide 4, being retained i'n this positionby theengagement of thelatch-plate 62 with the detcntlade 60 on the rockablerod 56. The thread-lifter 65 is rocked into the position shown in Fig. 3to release the detent-rod 56 and to act concurrently to lift the strand7/ out of the groove in the thread-guide 4 in the manner as laterexplained. This action of the Athread-lifter is. eiected through thecooperation of instrumentalities as next4 described.

Referring to Fig. 3, a bifurcated lever 77 is pivoted to the in- 40whichv supports the forward end of tiie slide 35 with its opposite legsstraddling the sides of the slide. The lever 77 has an elbow-shaped arm78` which vis formed with an inclined slot 79 engaged by a pin 80projecting from the side of the slide 35. When the slide 35 is slid intothe position shown in Fic'. 3 under the pressure of the spring 45 thepin 8O slides in the slot 79 to )tilt the elbow-shaped arm 78 of thelever77 upwardly. The end of the arm 78 of the lever 77 is hooked un-Ider al crank-arm 81 which, as shown in Fig.

1, forms part of a Wire rod 82 pivotally mounted in lugs 83 on the underside of the thread-lifter 65. The crank-arm) 81. has a i hook 84 at itsend to which is connected a wire link 85. T e link 85 is hooked beneaththe tail-piece 8 which, as shown in Fig. 3, is pivoted on a pin 89 andconstitutes the activeelement for rocking the thread-lifter to releasethe detent for the stopping-mechanism. `The lever 87 is constructed ofsheet-metal with -a bifurcated portion 88, the sides of which l straddlea lever 90 carrying the pivot-pin 89. The lever '90 is pivoted on a pin91 driven into the. side of the frame-member 6, see Fig. 1, and itsupper end is bent over at 92 to adaptit to engage a tail-piece 93projecting at an angle from one of the bearings of the thread-lifter 65.The tail-piece 86 on the lever 87 projects into position to of a.knoek-off lever 87'A ladapt its end to be enffaged'by atoothed collar orwheel 95 whic is secured to the cam shaft 27 to rotate therewith. A pin96 projecting from the side of the frame-meiner 6 limits the upwardmovement of the tail-piece 86 on the lever 87 whereby when the end ofthetail-piece is engaged by a tooth on. the wheel 95 the lever will bemoved bodily to rock the connected vlever 90 in the direction indicatedby the arrow a in Fig;` 3. This rocking action of the lever 90 bringsits heut portion 92 against the tailpiece 93 on the thread-lifter 65 torock the atterto raise the thread out of the threadguide while releasingthe detcnt for the stopping-mechanism in the manner as hereinafter morefully explained.

The lever 87 may also be rocked to engage its tail-piece 86 with thetoothed wheel 95 to arrest the winding operation when the strand breaksb f means of a breakage-lever 125, shown in igs. 1 and 2. The lever 125extends forwardly from the rod 82, being rockable on the rodindependently thereof. A collar 126 is fast on the rod 82 and has a slot127 in which the lever 125 plays. This arrangement provides that thelever 125 may rock upwardly without turnin the rod 82,

Abut when it drops it engages t e end of the slot 127 in the collar 126to turn the rod 82 to lift its arm 81. In this manner when thebreakage-lever 125 is released from the tension of the strand y it willdro to raise the arm 81 to cause it to act throng 1 the link 85, seeFig. 3, to carry the tail-piece 86 of the lever 87 into position to beengaged by the teeth on the rotating collar or wheel 95. Thisarrangement is similar to the usual breakagelever mechanism forarresting the winding operation when the thread or yarn breaks.

Manuall -operable means are provided for releasing t e cone-holder 3 toreturn it into driving connection with the drive-roll 2 and toconcurrently reset the stopping-mechanism to start the windingoperation. This manually-controlled means also operates to v return4 thethread-lifter toI normal position and the instrumentalities employed forthis purpose are illustrated in Fig. 4. They comprise essentially abifurcated frame 100 havlng opposite legs 101, see Fig. 1, pivoted onthe trunnion-pins which support the thread-lifter 65. The two legs 101of the frame 100 depend below the thread-lifter 65 and are connected bya cross-strip or web 102. Bolted to the cross-strip 102 is a curvedhandle or starting-lever 105 which reaches outwardly from the front ofthe ma chine in convenient position to be grasped by the operator.Referring to Fig. 1. the right-hand leg 101 of the frame 100 is extendedupwardly in an inclined arm 106, see also Fig. 4, .which has a flatplate-like portion 107 normally lying adjacent and in alinement with themain plate portion of the threadtid lifter 65. The plate`107 is curledover at the ttp in an extension 108, see Fig. 4, which is a apted toengage beneath the crooked portion 58 ot the detent-rod 56 to rock thelatter to engage its detent-blade 60 with the Llatch-plate 62. The arm106 of the frame 100 is also provided with a Web-like exten sion 109which is engaged by the hooked end 110 of the slide 35, see Fig. 4. Itwill thus be observed that when the starting-handle 105 is depressedinto the position illustrated in Fig.. 4 the traine 100 will be rockedto cause its arin 106 to slide the slide35 to move its dogging-arm 42into position to engage the quadrant 30. .During this operation thehnger or extension 108 on the arm 106 rocks the detent-rod 56 to engageits blade 60 with the latch-plate 62 and this rocking motion oit the rod56 also operates to rock the lever 52 to release the pawl 50 from theratchetteeth on the quadrant 30, the functioning ot these parts to startthe winding operation being more tully explained hereinafter.

A spring 111 normally holds the iframe 100 in the position illustratedin llig. 2 with its extension 108 bearing against a lug or rest 112 onthe bearing-block 18. The spring 111 is connected at 118 to the trame100 with its opposite end anchored to a pin 114 held in the side of theblock 18.

Referring to hig. 4, a bell-crank lever 115 is pivoted on the pin 91which 'lorins the pivn otal support itor the lever 90 and one ot' itsarms 116 reaches upwardly and is bent over in a linger 117- whichengages a hole 118 in a lug 119 at the end ot the cross-strip 102 oilthe trame 100. The lower arm 120 of the lever 115 is adapted to engagethe tail-piece 86 ot the lever 87 to depress the latter to hold its endtree trom the teeth on the wheel 95, the lever 115 being rocked toeffect this action as shown in liig. 4 when the starting lever 105 isdepressed to start the winding operation. rllhe method of operation otthe complete machine is as follows:

Assuming that the winding has been arrested with the copor cone-holder 3held in raised position above the drive-roll 2 throughthe means ot theratchet pawl 50 acting on the teeth 49 of the quadrant 30, the machineis prepared for operation by placing a paper shell or tube 'l on themandrel or holder'. The strand y of #yarn or thread is drawn up from itssource ot supply, not herein shown, and led under the reakagelever 125,thence across the upper edge of the thread-lifter and its end secured tothe cone-tube T.

With the winding operation arrested the parts of the stopping mechanismare in position substantially as shown in Fig. 3. To start the windingthe operator grasps the starting-lever 105 and presses it downwardlyagainst the tension of its spring 111, see Fig. 2, to the positionillustrated in Fig. 4.

The depression of the lever 105 rocks the frame 100 and the latter actsthrough its 4 that the friction-dog 42 is moved back to clear thequadrant 30 as shown at the right in this view. As soon as the slide 35has ,been withdrawn in this manner the further movement ot the rockingi'raine 100 causes its extension 108 to engage the crook or crank 58 atthe end ot the rod 56 to turn the latter to rock the lever 52 carried atits end. The lever 52 is thus rocked against the tension of its spring67, see Fig. 5, thereby causing the pin 47 to act against the pawl 50 tocause the latter to be swung away from the teeth 49 on the quadrant 30.lim mediately the pawl 50 is released the weight of the arm 10 and theparts carried thereby will cause the arm to swing downwardly on itspivot 11 to lower the cone-holder 8 to bring the surface ot the cop-tubecarried thereon into contact withthe periphery ot the continuouslyrotating drive-roll 2. The,

contact oit the cop-tube with the drive-roll will therefore cause thecop-holder or wind-` ing-mandrel to be rotated ytherefrom in thedirection indicated by the arrow 5 in llig.. 4. `its thecone-holder islowered against the drive-roll 2 the quadrant 80 slides down intoposition to adapt the dog 42 to be trictionally engaged with its convertsurface at'ter the slidev 35 has been released to allow it to slideforward under the'action oit its spring 45. 'lhis release ot thc slide35 does not taire place, however, until the startinglever 105 has beenreleased by the operator. Previous to this release of the slide 35 thedownward movement ot the lever 105 and the rocking action ot the trame100 caused thereby acts through the bell-crank lever 115 to cause thearm 120 of the latter to press the tail 86 ot' the lever 87 downwardlyto remove it trom possible contact with the toothed wheel 95.- rl'hisaction of the bell cranlt lever 115 thus serves to prevent nnwarrantedarrest ot the winding operation while the strand y oi thread on yarn isslack and the breakage-lever 125 droppedso that it will not free thelever 87 or, in other words, lower it away from the toothed wheel 95..

lt should be stated that when the threadlitterl 65 is tilted or rockedupwardly through the action of the lever 90 in arresting the windingoperation it is held in this position as shown in Fig., 3 by means ofthe blade 60 of the datent-rod 56 which slides along the inclined edge64 of the detent-plate 62 to the lposition shown in dotted lines in Fig.6. ln starting the winding operation, therefore, when the startinghandle105 is depressed to cause the eatenllll sion 108 on the frame I100 torock the crank arm 58 of the rod 56 the blade 60 will be slid away fromthis enga ement as last described to allow the threa -lifter 65 to dropinto the osition shown in Fig. 4 under the action ofp gravity. At thispoint the blade l60 on the detent-rod 56 is carried into ention to thethread-guide 4 that it will be picked up by the hook 29 on the guide toseat it in the oove 28 as shown in Fig. 1. This automatlc threadin ofthe threadguide takes place when t e uide reciprocates to the right asshown 1n Fig. 1, the traverse of the guide in the opposite directioncausing the strand to ride up over the curved portion of the hook 29 toadapt it to be plcked up at the next reverse movement of the guide. Asthe strand y of yarn feeds to the rotating cone-holder orWinding-mandrel 3 its slack is taken up and the breakage-lever 125 issuspended thereby to prevent it from influencing the breakagelever 87 tocause arrest of the winding operation. The operator can now release thestarting-lever 105 and the frame 100 will be returned to normal ositionas shown in Fig. 2 under the action of its spring 111. Wlth the parts ofthe mechanism set in this relation the winding operation will cony tinuewith the thread-guide 4 transversing the strand y back and forthlongitudinally of the cone-holder 3 to direct it onto the cop-tube T ina series of helical turns extending lfrom one end of the holder to theother and crossing each other at intervals. The cone or package is thusbuilt up with a series of overl ing layers of the helical turns of yarnor t read, the winding operation bein continuous until the yarn breaksor is eziliausted, or the package reaches a predetermined size. .l

Should the strand g/ break the breakagelever 125 will drop to raise thetail 86 of t e knock-off lever 87 into the position shown in Fig. 3 tooperate the stopping-mechanism of the machine in the manner aspreviously explained. Likewise, when the cone reaches a predetermineddiameter the stopping-mechanism is released through the disengagement ofthe quadrant 30 from the dog 42 in the manner as next ex ilained. As thequadrant 30 is carried up with the arm 1() supporting the cone-holder 3its end finally rides off from the dog or extension 42 of the rod 35.This permits the rod 35 to slide to the right under the action of itsspring 45 as shown in Fig. 3 and the pin 80 at the opposite end f therod will thereby act through the slot 79 1,eue,osa

in the lever 77 to rock the elbow-shaped arm 78 of the latter upwardly.The lever 77 is thus caused to act through the crank arm 81 and link 85to lift the tail 86 of the knockof lever 87 to bring it into osition tobe engaged by the teeth on the w eel 95. The ro-A tation of the wheel 95will therefore cause the knockoif lever-87 to rock the lever 90, thusacting through the tail-piece 93 on the thread-lever to tilt the latterupwardly to withdraw the strand y of thread or yarn from the threaduide4.

As before exp ained, the raising of the thread-lifter 65 releases thedetent-shoulder 61 on the plate 62 from the blade 60 at the end of therod 56, allowing said rod to be rocked under the action ofthe spring 67connected to the lever 52. The rockin of the lever 52 acts through thepawl 50 to orce the quadrant 30 upwardly whereby the arm 10 is raised tolift the cone-holder 3 t0 remove the cop or cone from contact with theperiphery of the drive-roll 2 as shown in Fig. 3. The rotation of thecone-holder 3 is thus arrested and the strand y of yarn or threadreleased from the thread-guide so that the winding ope-ration ceasesuntil the stoppingmechanism is manually operated again in the manner aspreviously explained. It has been before noted that the blade 60 on therod 56 slides along the beveled edge of the detentplate 62 to theposition shown by dotted lines in Fig. 6 to act asa holding-means tomaintain the thread-lifter in raised position until the windingoperation is started again, and in this Way the winding-mechanism ismaintained inoperative until the machine is prepared to wind again.

It will be observed from the foregoing that the invention provides anefficient means for controlling the winding operation automatin cally tocause the Winding to be arrested either when the strand breaks or whenthe cop, cone or package reaches a predetermined diameter. Theimprovement further provides that when the winding operation is beingstarted slackuess in the strand of thread or yarn, vibration of thebreakage-lever, or any other abnormal condition cannot act to causepremature or unwarranted arrest of the Winding operation.
